摘要：

An active noise control device reduces noise inside a cabin of a car. The active noise control device includes: a controller that decreases a signal level of a canceling signal when a signal level of a received reference signal is lower than a threshold； and a threshold controller that changes the threshold based on at least one of a signal level of an error signal and information on the car.
